Available in a variety of bright LED colors, the NiteHowl can be easily cut to fit, making it perfect for both big and small dogs. This dog safety necklace provides a full ring of illumination around your dog's neck and can be set to glow or flash mode to keep your furry friend seen and safe at night. Illumination has come full circle, literally. Our brilliantly durable NiteHowl LED Safety Necklace is made with flexible polymer illuminated by two bright LEDs (red, green, or blue), and simply slides over your dog's neck for hours of nighttime fun & safety. Just trim the tube to a custom fit, give the button on the durable, weather resistant housing a quick press, and the entire collar lights up a full 360 degrees, making your dog clearly visible from all angles. The LEDs can be set to either flash or glow modes - great for differentiating more than one NiteHowl-wearing dog. But, as fun as it is (like a neon necklace for dogs!), the best thing about the NiteHowl is that it keeps you and your buddy seriously safe on those after-hours walks, romps in the park, and campsite moon-howling sessions.
